The Characteristic Analysis of Vibration for High-Speed Train-Ballastless Track-Bridge System base on A Hybrid FE-SEA method

摘要：

　　A hybrid method combining FE and SEA was recently presented for predicting the steady-state response of vibro-acoustic systems.The new method is presented for the analysis of complex dynamic systems which is based on partitioning the system degrees of freedom into a global set and a local set.The global equations of motion are formulated and solved by using the finite element method (FEM).The local equations of motion are formulated and solved by using statistical energy analysis (SEA).The power input from the global degrees of freedom.This paper deduces the theory for the beam element, and Train-Ballastless Track-Bridge System provides an application, and it showed that the method yields very good results.
